Apprentice boss Lord Sugar has said that this year's candidates will be challenged more than ever.

Speaking about the new series, which continues on Wednesday, Lord Sugar revealed that the new tasks were "cranked up" in complexity, and would hopefully show the viewers how to start a business themselves.

"The complexity of the tasks is cranked up, the tasks are reflective off what the end game is," the boss explained.

He went on: "Each task also gives the audience an idea of what can be done. We've lost that culture of starting with just £100 and working for a day to turn into £200."

Lord Sugar also hit out at wannabe entrepreneurs who hung their hopes on becoming the next internet billionaire.

"We need to dispel the fast-buck mentality," he moaned. "Too many youngsters look up to Mark Zuckerburg and Bill Gates and wait to become one of them - but they don't realise that it's a trillion-to-one chance."
